PAM_GET_DATA(3)                               Linux-PAM Manual                               PAM_GET_DATA(3)



NAME
       pam_get_data - get module internal data

SYNOPSIS
       #include <security/pam_modules.h>

       int pam_get_data(const pam_handle_t *pamh, const char *module_data_name, const void **data);

DESCRIPTION
       This function together with the pam_set_data(3) function is useful to manage module-specific data
       meaningful only to the calling PAM module.

       The pam_get_data function looks up the object associated with the (hopefully) unique string
       module_data_name in the PAM context specified by the pamh argument. A successful call to pam_get_data
       will result in data pointing to the object. Note, this data is not a copy and should be treated as
       constant by the module.

RETURN VALUES
       PAM_SUCCESS
          Data was successful retrieved.

       PAM_SYSTEM_ERR
          A NULL pointer was submitted as PAM handle or the function was called by an application.

       PAM_NO_MODULE_DATA
          Module data not found or there is an entry, but it has the value NULL.
